We just moved to Teams. Calls/meeting inside our network have choppy video/voice quality. People outside the network have no issues. Only if the traffic traverses the UTM does it have issue.
Does anyone have a writeup on how to configure the UTM so it doesn't mess with Teams traffic?
We had a lot of customers with VoIP and Webconf issues (Teams, Skype for Business and Zoom). The magic trick for us was to disable SYN flood protection. The difference was huge.
L'UNICA SOLUZIONE PER ME è STATA QUELLA DELLA DISABILITAZIONE Protezione contro il flooding UDP
Ciao Luca and welcome to the UTM Community!
It would be interesting to see an extract of the Intrusion Prevention log when Teams, Zoom or WebEx is active. That might tell us what Exception was missing.
Cheers - BobPS Thanks for posting in Italiano - reminded me of the time when I lived in Paris and traveled all over France, Germany and northern Italia to participate in scherma competitions.
ITALIANO: HO IMPOSTATO 3 DIVERSE MODALITA' DI ECCEZIONI PERCHE' QUALSIASI COSA FACEVO NEI LOG
RISULTA SEMPRE UN BLOCCO CON IP APPARTENTI A MICROSOFT DIVERSI DA QUELLI INDICATI .
I SET 3 DIFFERENT EXCEPTION MODES BECAUSE EVERYTHING I DID IN THE LOGS
THERE IS ALWAYS A LOCK WITH IP APARTMENTS IN MICROSOFT DIFFERENT FROM THOSE INDICATED.
IT ALWAYS RESULTS A BLOCK WITH IP BELONGING TO MICROSOFT DIFFERENT FROM THOSE INDICATED.
I solved it as follows (see attachment):
The networks are:
1) 126.96.36.199/182) 188.8.131.52/143) 184.108.40.206/14
The service group included:1) TCP/UDP 3478:34812) TCP/UDP 50000:50059
HTTP & HTTPS I just took it fresh today because these ports are also usedBut I have to admit that I am not 100% satisfied yet. We still have quality problems again and again
so the problems are still there ...
YOU GIVE ME CONFIRMATION BY WRITING THIS:
But I have to admit that I am not 100% satisfied yet. We still have quality problems again and again..:
UDP flooding disabled was the only solution for me
Disable UDP flooding in general or only for certain networks?
Have you looked at my IPS rule again? It differs from hers a little. For example, you make an AND condition and not an OR condition.
Did you also create a firewall rule?
I would like to try again to recreate the right exceptions and the right firewall rules.
can you tell me better and in detail the exceptions in IPS and the firewall rules you have set ??
any rules or exceptions I have set have failed.
that's why I had to disable UDP flooding
Everything comes out of my picture & text
Guys, unless we look at an excerpt from the Intrusion Prevention log when you're having a quality issue, we can't even guess what the issue might be.
Cheers - Bob
do you mean me?
Ihr alle, Ludo
Logs and pictures are the best way to chase down an issue.
